    Black Holes in Simulated Dwarf Galaxies

     

    Recent discoveries of dwarf galaxies hosting active galactic nuclei (AGN) suggest that massive black holes (MBHs) may be a common occurrence in such low-mass systems.  I examine the occupation fraction and characteristics of MBHs in dwarf galaxies using the MARVEL-ous Dwarfs and DC Justice League samples of high resolution cosmological simulations.  Approximately 50% of MBHs in the dwarfs are off-center, as a result of being perturbed by a merger with another dwarf galaxy.  The simulations include a...

    Towards more robust and explainable neural nets: Beyond the black box

     

    Deep neural nets have achieved ever greater successes in recent years, but there is still a pervasive sentiment in our field that "they are black boxes" and "we will never understand them."  A thorough understanding is elusive, but we can conceptualize what a neural net is doing using familiar tools and concepts, such as probability distribution functions, fitting functions, and Bayesian statistics.  We can leverage results from the field of "Adversarial AI" to study...

    Abstract:   The Importance of Being Eccentric The dynamics of bodies on eccentric orbits largely determines the evolution of planetary systems and stars near massive black holes. In this talk I will review eccentric dynamics and demonstrate wide-ranging implications such as the orbital clustering of Kuiper Belt objects in the outer solar system (which motivates the planet nine hypothesis), ‘ double’ galactic nuclei, and the tidal disruptions of stars by massive black holes in post-merger galaxies.
